Airmax - ProAir Diffuser Membrane Stick - 510168

ProAir Membrane Diffuser Sticks are designed to replace the air stones found on older Airmax Aeration Systems. These high-performance pond diffuser membranes are virtually maintenance free and easily screw into your existing ProAir 2 or ProAir 4 Diffuser Plate. Each Membrane Diffuser Stick measures 6" in length and is 1.5" in diameter. Membrane Diffuser Sticks should not be used in combination with Airmax Air Stone Diffusers on the same aeration system.

PTFE Diffuser Stick includes stick, membrane sleeve and two black retainer rings. Retainer rings can be purchased separately when purchasing the PTFE Membrane Sleeve only.

Replace the diffuser stick if you observe visible damage or experience reduced airflow from your KoiAir Aeration Kit. The 6-inch long PTFE Non-Stick Membrane Sticks are virtually maintenance-free and fit the KoiAir Diffuser Plates.
